1982 Le Mans 24 Hours C-ERA [RESULTS IN PAGE 11]

[RaduST]

Well, at least the looks are spot on

I believe my naturally aspirated C class is also a little underpowered (or at least a little low on torque) and about 100 kg to heavy. The turbo GT is only five seconds slower that the unlimited C class.

[DuratecDriver]

In a final rush to set up the car semi-properly i tried a quick turbo engine to see the differences, definitely more powah, but a huge hit to the eco...still undecided. Don't know if I will have time to do a GT car.

Talking of weights, I'm almost sure mine weighs way too much, especially seeing the weight limit...mine it's waaaay too overweight than 700kg, sitting on around a ton and some kgs.

[RaduST]

700kg in unrealistic I believe. With a turbo engine I think one could bring it down to 970-980kg or so. Mine also weights 1100 kg.

Submitted, in the end I chose to use NA engines (yes did a GT entry too), soon I'll add some pics.

Edit: Here are them, there is my C Class Entry, the "M470 Corsa"



And the GT Class partecipant, the "L-MR Scuderia"

Specs for Gemina XIII - Ilmor Pa-X & Gemina XIII Lancieri GTT



Like I said, a turbo unit for the C class probably would have been a far better idea.

[strop]

I simply couldn't find a way to get a turbo unit with good enough economy not to at least double my number of pit stops for infinitesimal gains. Even over 350 or so laps it didn't actually improve anything. So I also went with NA because the power outputs were pretty decent. I think my stats are very similar to radust's.

[Razyx]

I also went to the NA option... nice top speed on the Gemina XIII Lancieri GTT .

My GT entry - Haia GT - (and the strips looking good again uff!! hehe)

[RaduST]

That's one of the most badass cars I've seen around here.

700bhp...I was lucky to get in the 600bhp league...

I'm so going to wind up dead last...like Lotus at Indy 2012.

Maybe not, we'll see.

TY, the aerodynamicist was a bit crazy in that era

How are pit stops going to be calculated? Also don't we need to know the capacity of the fuel tank and divide that by the XX liters/100km

[RaduST]

This is a excel sheet with the formulas used in the '74 edition. Personally I think we should used a fuel consumption multiplier because it is a bit unrealistic to think that a 700 hp car would need less than 10l/100km in a race.

Oh my god, that looks wicked. I think Nightfury is due for a bit of a restyling...

vmo posted his method here: viewtopic.php?f=39&t=5330&start=20#p57751

I actually referenced it, and yes, I agree with RaduST. When I was doing my own calculations for a tournament idea and contemplating the factors in even a 2 hour race (the original concept of the BSLL lol), I thought the best way was to multiply the fuel requirements by 3-4 times.

EDIT: As raduST has posted stats and entries are now closed, I would take this opportunity to share as well.

There's a hint in the picture of the car... I don't know if it's competitive, but I managed a significant cut in lap time over the '74 times using a couple of tricks... for some reason the car doesn't really care about the rear downforce (probably because the car's tail heavy), but the front coming up ruined high speed cornering so bad it goes 4 seconds faster around Sans Chicanes with this setup... and aero set to zero!

As somebody else said, when going with a 718hp setup, the car ended up going slower than with my current 707hp setup. I think that's because while I have less top end power due to the reduced stroke, I have a higher rev limit, so upshifting puts my car at a place in the powerband. In addition, having learnt the trick from nialloftara, I double-baffled the exhaust, the flow restriction makes a small but noticeable boost in lower end torque.

Strop, if you really managed a 4 second improvement over drake's 3:50 from '74, then my Pa-X will be destroyed
Actually not funny. I most admit I didn't thought about adding a front lip. My very simplistic strategy was focused only on reducing drag and increasing power/torque.

Nah not quite 4, but like you were saying, without a few tricks (the skinny front tyres helped too), I was going significantly slower than Drake's car from '74 and wondering WHYYYYYYYYY THIS IS SUPPOSED TO BE 8 YEARS BETTER

But then yeah as I posted earlier, I had this eureka moment. The question will be how many other people figured it out too. I suspect if Drake is in on this round, he'll know the real inside angles.
